The invention relates in generalto ice cream containers, packages, andthe like, and refers moreparticularly to an improved' die-cut ice cream brick wrapper andcarton.

' l 1 cream brick. vThe slotshowever, provide a liner. 1 Icev cream is packed forcommerciaL-distribution` by forming*v a 'cardboard cartony having a waxedpaper liningand pouring semi-frozen lice cream intothe container thus formedthrough anopen end. This end is then folded shut*A and the filled carton placed intoalrefrigerator andfrozen into solid' form. "It is desirable, from both ahygienic and-an economic standpoint, to packagev theV nated and the benets-of-mass production'se-L cured. Various forms of carton lliner are now on the market, all of which are more for less unsatisfactory because of'the tendency of the liner to ltear Whilev being foldedy for insertion in the carton. The liner isi'irst wrapped about a mandrel comprising a Wood block ofa shape` and size equal to that of the finishedbrick. The liner wrapped mandrel is then inserted into ther carton andthe mandrel withdrawn leaving the 'liner frictionally engaging the linner sides of the carton. After theice cream hasv been poured'in and 3o frozen the carton liner becomes a brick wrapper and is removedzfrom the carton together with the brick when the latter is lremoved for l consumption. The Wrappers nowv iised com-- prise substantially.rectangular sheets of waxed paper of length sufficient to enfold the sides of the mandrel and having sufficient width between longitudinal edges to cover thesidesofthe mandrel and to extend therebeyond, to provide al surplus `at each end 4L0 which may be foldedl over to cover the ends ofthe mandrel. To facilitate the folding'of these end portions over the brick ends, the

pery is thus divided intosegments having lengthsequal tothe width ofthe brick sides and providing iiaps which may easily' be: V i

folded over'the ends of the semi-fluid ice starting point for tears, and if 'the linenis not placed in exactposition aboutthe man drel so that theslots are disposed opposite the cornersthereof, lor .if the liner is improperly positionedwithin the carton, strains will be inducedV in the'liner. material. Yand the liner may become so torn or, otherwise aged as to require re] ection of the package., .4.

fr The cut flaps alsoprovide aisource of faulty'folding. Since the flaps have perpen? dicular sides, their outer corners will proJectv beyondv the planeofthe adjacent side'offthe` container` and. engage adjacent ajps,l`if the Wrapping hasv not'beenyapplie'dzfwith accuf i racy, or if thecartonsisslightlymisdshaped. Such a-'projecting portion maycatch `-upon the carton ,or upon the Wrapping machinery andbecome torn; or, if the wrapping-,is suce.

some variation in the positioning.V of thelin'er therein. i v Another important object is they provision of an improved insert liner'for iceV cream cartons having tapering slots to provide convenienty iaps for folding about 'the end offay y mandrel or a poured icefcreambrick toy eli'mi nate tearing ofthe linermaterial.v c

Still another important object ofthe in,- vention is the provisionof a'linercforice cream cartons `having slots formed therein to facilitate the folding of the wrapper about the end of a `mandrel ora pouredice cream brick, which slots are Vprovided with rounded 55 Y19 dispos'edoneach side ofi-the mid-section T20*V M I preferred r`formoffthe*slotted,portion of ythe apeXes to'prevent tearing of the wrapper at that point duringfolding voperations and t0 allow the'linerto successfully accommodate VYslightlvariations in Athe dimensions of the lined icecream carton.

This situation is encountered even When the carton is perfectly formed if the liner is not inserted in the carton having inner slot ends coinciding With the corners of the carton. Another important defect is noticeable if the final Wrapper folds are improperly made. If a iap is not folded exactly along the line 36, the corners of the flap project laterally and engage adjacent flaps making the folding diiicult.

To overcome these disadvantages I have provided a liner having specially shaped slots 13, the sides 14 of which are spaced apart and the inner ends 15 of which are formed as rounded heads. In the preferred form of slot the sides 14 converge to an apex. The rounded apex provides a maximum resistance to tearing, and also allows a slight adjustment of the liner Within the carton to accommodate slight variations in the size and shape of the carton. The spacing of the sides of the slot provides end iaps having sides which Will not engage or interfere with the adjacent flaps or project beyond the plane of the sides of the carton if the flap is misplaced in folding.

It is thought that the invention and many of its attendant advantages Will be understood from the foregoing description, and it will be apparent that many changes may be made in the form, construction and arrangement of the parts Without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. An ice cream brick Wrapper and carton liner, comprising a sheet of Wrapping material provided With slots extending in from an edge and setting ofi' aps, said slots having rounded inner ends.

2. An ice cream brick Wrapper and carton liner, comprising a sheet of Wrapping material having a straight edge and a slotted edge, the straight edge being foldable to provide a closed bottom, and the slotted edge providing flaps to close down upon the top of the brick of ice cream, said flaps being separated by slots having rounded inner ends.

3. The method of folding a Wrapper about the end of a brick of ice cream which comprises providing a plurality of V-shaped slots having rounded apices in an edge thereof, to provide a plurality of fiaps at the slotted Wrapper edge, folding to rectangular form With the aps extending and then folding the flaps over the end of the brick of ice cream.
